I think it's better to have the iteration of vectors (elt of
module-with-basis) return pairs of ``(index, coefficient)`` (over some
fixed total order on the basis index set) since this will be compatible
with their infinite dimensional analogues (where I do use the iteration
quite a lot). Note

I'm not so sure of that particular name! "iterating" over an elem

It is, but the functionality is still provided by .items() . So the
discussion of what the semantics in sage should be, is still relevant.

iteritems() is gone in Python 3...

I have been dreaming of this change for quite some time. I don't have
an opinion on whether it's acceptable to c
IMO we should swap the order of the pairs. It would make it consistent with
other parts of Sage too:
sage: C = CombinatorialFreeModule(QQ, ['a','b'])
sage: x = C.an_element()
sage: list(x)
[('a', 2), ('b', 2)]
sage: F. = FreeAlgebra(QQ)
sage: list(2*x + y)
[(y, 1), (x, 2)]
Best,
